Is this an idea for a alternative coin or something? I only ask this because the amount of double spends under normal circumstances is zero. I think the only real double spend happened during the blockchain fork.

I might be wrong but Bitcoin is not suffering from any double spend issues and the developers are best focusing their efforts into fixing real problems with Bitcoin.

However if your idea can be incorporated into a alternative coin that did not require massive amounts of useless work to support the security of the network, then you might be onto something...
